Are you wondering, Why my AC is making weird noises? In this article, we will go
over common weird noises that could be coming from your AC that are abnormal
and require attention.
An
AC making weird noises is not only annoying but can also lead to larger
problems down the road if left unchecked. That's why it's important to know the
common noises that indicate you may need an AC repair service or replacement.
Rattling
First
and foremost, rattling noises can indicate that loose objects are coming into
contact with the unit. For example, such loose objects could be leaves, twigs,
or rocks. Or, parts of the unit (e.g.,
panels, screws, bolts, etc) have come loose. If this is the case, more
parts could become loose, causing even more problems and long-term damage.
Additionally,
a rattling noise could be caused by a malfunctioning compressor. In this
scenario, you will likely notice that your home is not cooling as effectively
as it once did. Compressor problems should be left to diagnosis by a licensed
and trained professional.
Further,
when you have rattling noises, you could also have to malfunction AC motors
caused by damaged bearings or poor lubrication. There could also be misaligned
fan blades in your unit. Again, under these scenarios, you will want an HVAC
professional to diagnose.
As
you can see, there could be numerous explanations behind rattling noises. Thus,
if your AC is making such noises, it's time to have a licensed air-conditioning
technician inspect your unit, identify why the noise is happening, and fix it
accordingly.
Buzzing
If
you hear a buzzing sound from your AC unit when it's running outdoors, this
should not be overlooked, as it can indicate an electrical problem with your
unit. There could be a problem with your components, such as a faulty condenser
fan motor, faulty compressor, or isolation feet issues.
If
you hear a buzzing noise from the indoor air-conditioning unit, you could have
an issue with frozen evaporator coils. It's best to have a licensed
professional perform a proper diagnosis for a buzzing noise.
Squealing
Are
you hearing new squealing noises from your unit? This may be from a mechanical
issue such as a worn-out compressor, fan motor, or blower motor. Additionally,
worn-out fan belts can cause squealing.
Hissing
Hissing
noises are also not normal.
Hissing
could indicate an air duct leak in your home. This noise could also indicate a
refrigerant leak. The refrigerant in your AC unit is under pressure, so, when
it leaks, it makes a hissing noise, which should not be ignored. The longer you
let a refrigerant leak fester, the likelihood of larger problems and costlier
repair bills.
When
you hear hissing, it's time to schedule service with an Atlanta HVAC technician.
Grinding Noise
A
grinding noise is a serious noise that can be a cause for concern. If it's coming
from an outdoor air conditioner unit, it could be from the following:
● compressor issues;
● a loose blower fan belt;
● or lack of motor lubrication.
A
grinding noise is reflective of the need for AC services, and you should have a professional
properly remedy the problem.
